is there a Forum for ACPI? I looked at the EFI website which claims to be a Forum but it's not. or atleast it's not publicly available for viewing.

it looks like there is an error in the AML 'Byte Stream Byte Values' Table. on page 848 (ACPI 5.1 Release) the first entry in the table (the table starts on the previous page) for that page is "MethodOp". MethodOp is described as being followed by a NameString, ByteData, and TermList. this contradicts the (far more difficult to find) "DefMethod" (page 841) which is defined as being followed by PkgLength [Package Length], NameString, MethodFlags, TermList.

basically; Package Length is missing from the table entry on page 848.

btw; I'm using VMware to build an AML parser and it looks like VMware uses the "DefMethod" description.

found another one. the ScopeOp is also missing the Package Length in the table version.

Have you tried phoning/emailing the authors? There seems little reward for you if you only post it here. Unless you are sure the authors read this board?

my question was about finding a forum for ACPI. so no; contacting them was not on my mind. I happen to prefer the forum environment.

also; I found more. none of these report a PkgLength in their AML Table entries but all of them have one in their "Def" form:

DeviceOp
ProcessorOp
PowerResOp
ThermalZoneOp
IndexFieldOp
BankFieldOp
